Tap to choose an image or photo. If you select a photo, drag it to adjust its position, and then open or close two fingers to zoom in or out until it looks satisfactory.
Tap Settings, then choose whether to use photos as wallpaper for the lock screen or the home screen. In addition to setting the wallpaper with the photos that come with the mobile phone, we can also add more photos to the iPhone from the computer. Let's take iFunbox as an example to demonstrate how to add pictures from the computer to the iPhone. Open iFunbox and select wallpaper from connected devices.
Select Copy from Computer, and then select the photos you want to transfer to iPhone on your computer. Photos copied to this location will be automatically cropped to fit the resolution of the iPhone screen. After the synchronization is completed, just select the previous photo in the wallpaper option and set it as wallpaper.
